Hi all,

I'm seeing some weird messages in /var/log/messages when inserting my USB2.0 flashdrive. Apparently scsi.agent cannot determine the type of scsi device that is created by usb-storage. When I leave the stick in during boot, it works fine.

Software:
* Mandrake 9.2 base system with some modifications:
* Kernel 2.6.0-test11 (also tried kernel 2.6.0-test11-bk8) SCSI and USB compiled as modules.
* Hotplug 20030805
* udev 008
* sysfs mounted on /sys

Hardware:
* Canyon USB2.0 (high speed) 128 MB flashdrive, with an embedded hub.
* EHCI controller (UHCI controller gives same problem)

I think what happens when inserting the flash drive is this:
hotplug sees the embedded hub and mass-storage device in the USB stick and loads usb-storage and SCSI modules. Then it seems that scsi.agent tries to extract a number from the file /sys/devices/<.....>/type
which appears to be an empty string according to the log. When I try to cat this file manually, it exists and it results in the number 0, which correctly indicates a SCSI disk with associated module sd_mod.
I can imagine that this is some kind of race condition, where the script looks too soon for the file or its contents.

Is this a known problem?
What kind of logging / information is required to investigate this?

Kind regards,
Bertrik Sikken

Yeah, I've seen this a lot too. userspace is a lot faster than the kernel in this instance :)

Exactly. Try putting a sleep before reading the file, or loop on the file for a bit before reading it.

I can confirm that the sleep works (added a sleep 1 at the start of the script). Does this suggest an issue in the kernel?

B.T.W. I forgot to mention that the pre-empt was enabled in the kernel.

Thanks,

No, it's not a problem with the kernel, it's just something that you need to be aware of in your hotplug scripts.

You need to make sure that user space loses the race.

Shouldn't this actually be two separate hotplug events?

One when the unit is physically attached, to load the usb-storage driver.

The second when the SCSI layer has initalized the device, to run the scsi.agent?

Actually, udev cares about the _third_ event :)

The one where the block device is created in sysfs. The problem is that the block device is created, hotplug is called, but the scsi core hasn't finished populating the sysfs tree with the files for the scsi device yet. It's not that big of a deal, as it's easy to detect in userspace, I just haven't added it to udev yet...

Is your device seen as a block device? If so, do you react on the block event or on the events before the block event? I'm almost sure you care about stuff like 'sdX' or similar. So doing something from usb.agent or scsi.agent is obviously wrong. Use a block.agent script.

I don't see why doing something from usb.agent or scsi.agent is obviously wrong. As far as I understand, plugging in the device causes a USB hotplug event which triggers loading of the usb-storage module. This in turn fires off a SCSI hotplug event which should load the sd_mod module and create a block device. From then on, its up to the user (me) to mount the device.

I see the same. The reason is probably in scsi_probe_and_add_lun(). It calls scsi_alloc_sdev() which seems to generate the event, and later it calls scsi_probe_lun() which seems to set the type.

Quoted 2 lines

I can not find a block.agent script in the default hotplug script. Why do you think I need it?

block.agent is (eventually) needed for other reasons. You need sd_mod to get a block event.

I can't find the email you're replying to (in my inbox or the archives, anything dated Jan 02 from Bertrik).

scsi_add_lun() calls scsi_sysfs_add_sdev() for the scsi_device after it has set the type, and there we have the race between the hotplug event generated via the call to device_add() and the addition of the attributes for multiple calls to attr_add().

The type is initialized to -1 in scsi_alloc_sdev, so at worst you might see a -1 there, but that would be a bug.

Are you hitting the problem even after adding the sleep 1 hack?

sleep 1 cures it, sometimes it does even work without the delay. I check it again in a few hours.

Hello,

I'm not sure if this bug was fixed or not. But I see a related race (block hotplug events triggered too early).

If the partition table is not yet scanned (according to syslog output), udev fails to detect the main device sda as a scsi device and falls back to usb. all partitions on that drive match the BUS="scsi" rule, just not the main device, it matches BUS="usb".
Creating a block.agent and putting a 'sleep 2; /sbin/udev block' in there will fix it, sleep 1 is not enough.

kernel is 2.6.2-rc2-mm2

BUS="scsi", PROGRAM="/bin/echo a-%M:%m", NAME="%k" SYMLINK="debug-scsi-1-%1c debug-scsi-2-%2c " BUS="usb", PROGRAM="/bin/echo b-%M:%m", NAME="%k" SYMLINK="debug-usb-1-%1c debug-usb-2-%2c"
